Program Managed by Joint Program Office for Chemical and Biological Defense

Jun 17, 2005

WILMINGTON, MA, USA - AMETEK Aircontrol Technologies has been awarded a test and evaluation program for a regenerative filtration system under the U.S. Department of Defense’s (DoD) Joint Program Executive Office for Chemical and Biological Defense (JPEO-CBD).

The program award follows more than 10 years of internal research and development by Aircontrol Technologies on regenerative filtration systems aimed at replacing the throw-away carbon filter systems used by the U.S. DoD, U.K. Ministry of Defence and NATO. Unlike conventional NBC filtration systems that are not regenerative and must be discarded and replaced following an attack, a Pressure Swing Adsorption (PSA) regenerative filtration system uses filter beds filled with sorbent materials, which adsorb gases under pressure and desorb them once the pressure is removed.

A PSA regenerative filtration system provides multiple benefits. Military vehicles can operate in chemically and biologically contaminated environments without replacing carbon air filters. That reduces the logistical burden of carrying additional filters in each vehicle. The PSA-based technology also provides protection against a wider array of toxic chemicals and agents than conventional carbon filters.

A typical PSA system has two filter beds, one on stream, which is fed with contaminated air under pressure absorbing gases, while the other off-stream bed is regenerating. The desorbing gases are purged from the system with clean filtered air. Every eight seconds, the role of each bed is reversed. That cycle continues with the pressurized contaminated air swinging from one bed to the other, with the operation controlled by an automatic sequencing timer to ensure continuous filtration.

In 2004, Aircontrol Technologies was awarded a contract by the U.K. Ministry of Defence for a Regenerative Filtration System for the TERRIER® armoured engineer vehicle under development for the British Army. The TERRIER is the world’s first military production vehicle to be fitted with an advanced integrated Crew Temperature Control and Regenerative Pressure Swing Adsorption CBRN Filtration System.

The U.S. DoD selected Aircontrol Technologies for full participation within the air purification focus area of the Collective Protection Technology Readiness Evaluation (ColPro TRE) program that includes performance testing and evaluation. The ColPro TRE program is conducted and funded under the management of JPEO-CBD and the Joint Science and Technology Office for Chemical and Biological Defense.

The JPEO-CBD was formed in 2003 to focus on the protection of soldiers, sailors, airmen and Marines from battlefield chemical and biological weapons. It is the first-ever joint program executive office of the Department of Defense encompassing as many diverse programs, over a wide scope of responsibilities, and serving the needs of all of the armed services.
